With Merrin I guess it's how much they paid and what role he will play. I think most teams like experience on the bench so if he's going to be an experienced bench player who occasionally gets a start AND he is playing decent I think it's good.
He was pretty woeful at Penrith though. How has he gone at Leeds? Also, maybe more importantly why haven't the Dragons signed any backs for 2020? A backline of Sailor/Dufty, Sailor, Lafai, Aitken and Lomax is without question the worst backline in the comp. Even players like Curtis Scott would be major upgrades for that backline.
